A passive optical network includes a central office providing subscriber signals; a fiber distribution hub including an optical power splitter and a termination field; and a drop terminal. Distribution fibers have first ends coupled to output ports of a drop terminal and second ends coupled to the termination field. A remote unit of a DAS is retrofitted to the network by routing a second feeder cable from a base station to the hub and coupling one the distribution fibers to the second feeder cable. The remote unit is plugged into the corresponding drop terminal port, for example, with a cable arrangement having a sealed wave division multiplexer.

The present disclosure relates generally to a fiber optic jumper including a fiber optic cable that extends between first and second cable ends. The fiber optic cable includes a cable jacket containing at least first and second optical fibers. The fiber optic jumper also includes an optical transceiver module directly terminated at the first end of the fiber optic cable, and at least one fiber optic connector directly terminated at the second end of the fiber optic cable. The fiber optic jumper is outdoor rated for temperatures ranging from minus 40 to 75 degrees Celsius.

The present disclosure describes active optical cable assemblies. A cable assembly includes a fixed active optical connector having a transceiver, a ruggedized optical fiber cable integrated with the fixed active optical connector, a main cable assembly comprising one or more optical fiber cables, wherein the ruggedized cable is spliced to the main cable assembly; and a removable shroud configured to surround at least a portion of the fixed active optical connector plugged into a remote radio unit and to be secured to a remote radio unit. Active optical cable and remote radio unit systems are also described.

The present disclosure describes sealing boots for protecting an optical interconnection. A sealing boot may include a main body having an interior cavity, the interior cavity having an annular recess adjacent to one end of the main body, the annular recess configured to receive a feature of a remote radio unit, and a neck merging with the opposing end of the main body and having a cylindrical inner surface that defines a bore that is continuous with the cavity of the main body, the inner surface having an inner diameter that is less than an inner diameter of the interior cavity of the main body. The sealing boot is configured to surround at least a portion of a fixed active optical connector when the fixed active optical connector is plugged into the remote radio unit.
